BACKGROUND
NA-AION is a condition that exhibits a number of unique characteristics in diabetics compared with the rest of the population. In some diabetic patients with NA-AION, lipid deposits can be observed around the macula forming an incomplete macular star.
METHODS
We describe 12 case studies of patients with NA-AION observing the development of lipid deposits around the macula forming an incomplete macular star.
RESULTS
All our patients developed some level of lipid deposits around the macula in the form of a macular hemistar in the course of their illness.
CONCLUSION
Some authors have suggested that the macular star is formed by transudation from capillaries deep in the optic disk through the intermediary tissue of Kuhnt, which is located between the retina and the anterior portion of the lamina retinalis. However, the development of the macular star is currently understood not as a simple transudation but as a multifactorial process involving the presence of vascular damage around the optic disk, which is considered one of the most important factors leading to its occurrence. Although some studies mention the presence of a macular star in patients with NA-AION, we believe that this phenomenon may be significantly more common than the current literature suggests.
背景
非动脉炎性前部缺血性视神经病变（NA - AION）在糖尿病患者中表现出一些与其他人群相比独特的特征。在一些患有NA - AION的糖尿病患者中，可观察到黄斑周围有脂质沉积，形成不完全的黄斑星。
方法
我们描述了12例NA - AION患者的病例研究，观察黄斑周围脂质沉积形成不完全黄斑星的发展过程。
结果
所有患者在病程中均出现了一定程度的黄斑周围脂质沉积，表现为黄斑半星。
结论
一些作者认为黄斑星是由视盘深部毛细血管通过位于视网膜和视网膜板层前部之间的昆特中间组织渗出形成的。然而，目前认为黄斑星的形成并非简单的渗出，而是一个多因素过程，涉及视盘周围血管损伤的存在，这被认为是导致其发生的最重要因素之一。尽管一些研究提到NA - AION患者中存在黄斑星，但我们认为这种现象可能比当前文献所显示的更为常见。
